This calculator does not calculate emissions from non-emergency engines. Contact your reviewing authority if you use non-emergency engines to power your operations. If the throughput capacity of a piece of equipment limits (or bottlenecks) the maximum throughput of other equipment, then input the bottlenecked capacity of that other equipment, but only if it impacts output of product. **Facility Profile Control Technology Used (Y or N) ** * **Potential To Emit Calculator for Sawmill Facilities** 7/2/2014 This spreadsheet helps estimate a facility's potential to emit. It is provided for the convenience of the permitted community. Emission factor sources are subject to revision or correction. It is the permittee's responsibility to determine their emissions. The permittee should consult with the reviewing authority to determine the appropriateness of this calculator for its source. Enter the facility's information below. Wr ite the letter "Y" or "N" next to each fuel type to indicate that the facility does or does not burn that type of fuel. If you operate multiple facilities of the same type (more than one wood-fired boiler or more than one drying kiln), enter the total rated capacity. Enter the maximum capacity information for the equipment at your sawmill.
